That’s what I hear. But the button that engages the diff lock is physically stuck down. The wheels are locked together, however not completely. Not realizing it was stuck in while moving snow, I was using the brakes to steer the tractor. I realized it was still stuck in when I heard some awful noises while turning, and looked down to see the button still down. Otherwise, the diff-lock did seem to help keep traction so I’m assuming it was working as it should up till now.
